Hi George,

Sending to the list....

Generally speaking, -D and -I options should be assigned to CPPFLAGS.

CPPCLAGS is used by th preprocessor, the C compiler, and the C++
compiler (and other things that use the preprocessor like asm files
with the .S extension).
CFLAGS is used by the C compiler
CXXFLAGS is used by the C++ compiler

-L tells the linker where to find libraries, so it should be added to LDFLAGS.
-l adds a library to the list of linker libraries and should be added to LDLIBS

Options like -Wall are compiler options and so should be added to
CFLAGS or CXXFLAGS
